Microsoft has added yet two more companies with Android- and Chrome OS-based products to its patent-licensing list.

The latest additions, which Microsoft announced on July 9, are Aluratek and Coby Electronics. Microsoft officials said as of today's latest signees, "Microsoft has licensed more than 70 percent of all U.S. Android devices."

As part of today's deals, Microsoft will be receiving undisclosed royalty payments from both vendors.

Microsoft's claim is that Android and Chrome OS violate publicly-unspecified Microsoft patents and companies that are choosing to build products around these Google operating systems are making a risky bet.

Microsoft has convinced a number of Android and Linux-based device makers that it's better and cheaper to pay than fight. Among those companies with Android- and Linux-based devices that have capitulated are Amazon, Buffalo, Compal, General Dynamics, HTC, LG Electronics, Samsung, TomTom, Velocity Micro and others.

Barnes & Noble was a holdout, refusing to sign a patent deal with Microsoft, but a coule of months ago, opted to settle and sign with Microsoft. Microsoft invested $300 million in a new joint venture with B&N as part of that settlement.
